## Function Documentation

## ftdi_readstream()

int ftdi_readstream | ( | struct ftdi_context * | ftdi,
|  | FTDIStreamCallback * | callback,
|  | void * | userdata,
|  | int | packetsPerTransfer,
|  | int | numTransfers
| ) |  |

Streaming reading of data from the device

Use asynchronous transfers in libusb-1.0 for high-performance streaming of data from a device interface back to the PC. This function continuously transfers data until either an error occurs or the callback returns a nonzero value. This function returns a libusb error code or the callback's return value.

For every contiguous block of received data, the callback will be invoked.

Parameters

  ftdi | pointer to ftdi_context
  callback | to user supplied function for one block of data
  userdata |
  packetsPerTransfer | number of packets per transfer
  numTransfers | Number of transfers per callback
